3. Introduction
Back in 1990, a program which played music on the HP-28S was developed by
Shimpei Yamashita. The program required a list of complex numbers in the
form
(f,d) where f was the frequency and d was the duration. The program
worked
well for playing music, but when the program was rewritten for the HP48SX,
easier ways to make music or lists for the program were sought.
Yamashita then
came up with the "MusicWriter Special," a program which eliminated the
need to
calculate frequency or use cumbersome tables. Just by simply entering
note
names, tempo and beats, the MusicWriter Special would translate the data
into a
list which can be read by the music playing program.
Within a year, I introduced two additional versions of the MusicWriter
program.
MusicWriter version 2.0 brought new features such as a stack-oriented
environment, which displayed up to four notes at a time, a "delete"
command,
which erased the last note entered, and a menu-driven input capability,
which
made entering note names much easier. I released a second version of the
music
playing program "PLAY" shortly thereafter. The new version of PLAY
reduced
very small but noticeable gaps between notes but required a list which
was not
compatible with those created by the MusicWriter Special or MusicWriter
version
2.0. MusicWriter version 3.0 was designed to create lists which were
usable by
the new PLAY version, but was otherwise exactly the same as version 2.0.
In 1992, MusicWriter version 4.0 and MusicWriter Pro version 1.0 were
released.
Both were designed to be more flexible and easier to use than previous
versions. Features such as a seven-note "stack" display and insert and
delete
functions were added. A cut/copy/paste feature was also added to
MusicWriter
Pro version 1.0. Unfortunately, because graphics were used heavily for
these
programs, they were also the largest and slowest versions.
You no longer need a HP-49 math coprocessor or a graphics accelerator
board
with MusicWriter version 5.0 and MusicWriter Pro version 2.0. These two
versions are not fast or small, but compared to MusicWriter version 4.0
and
MusicWriter Pro version 1.0, respectively, they are faster and smaller.
The
consequence is that the "stack" display has been reduced to five, and the
appearance of the display looks less organized. Several features have
been
added, however, including a help screen and an off switch. The help
screen is
provided as a memory refresher and not as a tutorial on how to use the
program.
Therefore, it is strongly recommended that you read the documentation
before
using the program. Some potentially dangerous bugs and flaws have also
been
corrected, and the libraries now include two new programs, GC and MC.
If you do not care about writing music for the HP-48 but would like to
hear the
samples, you are welcome to do so. Install one of the two libraries and
download a sample directory. Recall a selection to the stack, decompress
using
the appropriate program (RFU or MC) and execute MPLAY. For detailed
instructions, see section 7.
4. Credits
One of the many special thanks goes to Joe Horn, whose Goodies Disks have
helped me better understand and gain access to the internals of the HP48. I
would also like to thank Rick Grevelle (most of the programs were
developed
using his Hackit Library) and Lutz Vieweg (the Redundance Fighter
programs are
utterly amazing). Finally, I would like to thank Shimpei Yamashita, who
started it all with the original MusicWriter Special.
5. Installing and Uninstalling
To install the MusicWriter Library, download either the MWRTR20.LIB file
for
MusicWriter v5.0 or the MWPRO20.LIB file for MusicWriter Pro v2.0 to the
calculator in binary form. Recall the contents of the variable to the
stack
and execute DUP. Check to see if the library object is valid by
executing
BYTES. The library object for MusicWriter v5.0 should be 3435 bytes with
a
checksum of # E764h or # 59236d, and the library object for MusicWriter
Pro
v2.0 should be 6841.5 bytes with a checksum of # 8C4Eh or # 35918d. Do
not use
the library if the figures do not match. Store the library object in a
port by
placing a port number such as 0 on the stack and executing STO. Turn the
calculator off and then on. The calculator will perform a system halt,
and the
library will automatically attach itself to the home directory. You may
now
purge the variable in which the library was stored.
If you would like to remove the library, place a tagged object on the
stack in
the form x: 1151 for MusicWriter v5.0 or x: 1136 for MusicWriter Pro v2.0
where
'x' is the port number in which the library was stored. Execute DUP,
then
DETACH, then PURGE.
When downloading the sample directories, be sure to do it in binary mode.
The
samples are listed in section 7.
6. Program Descriptions
The contents of the MusicWriter libraries are very similar. Both have
the
following: MPLAY, a music playing program; MADJ, a music adjustment
program;
MC, a music compression program; GC, a "garbage collection" program. The
library with MusicWriter v5.0 has MW50 and MWV in addition to these, and
the
library with MusicWriter Pro v2.0 has MWP20 and MWPV.
6.1. MW50 and MWP20
These two programs assist in writing music for the HP-48. They create a
list
of complex numbers in the form (f,d) where f is the frequency in hertz
and d is
the duration in seconds. (261.4, 1) for example, would represent the
note
middle C for one second. Since each one of these complex numbers
represent a
single note, the more notes there are, the larger the list. The program
MPLAY
uses this list. It "plays" the contents of the list starting at the last
complex number. The programs MW50 and MWP20 are designed to help the
user
write music without the use of frequencies and durations. Of course, the
user
must have a general knowledge of music (such as note names, beats, and
ability
to read music).
Make sure that the last stack option is enabled and start MusicWriter by
executing either MW50 or MWP20 (depending on which one you have). If you
have
MWP20, you should see three menu options: NEW, EDIT and EXIT. EXIT quits
the
program. NEW starts a new list with the default values: middle C for 1
second.
EDIT allows you to edit a list previously created by a MusicWriter
program or
created manually by the user. To edit a list, the list must be in stack
level
1 before running MWP20. For now, just press NEW.
The screen should now be displaying "CS Nt Reg Dur
Tmp" or "C Nt Reg
Dur
Tmp" at the top, "CN 3
1
60" in the middle and "1 of 1 S" at the
bottom.
The top line is called the Field Bar. This line shows the field names
for each
column. "C" stands for Current Entry; the note with the arrow in this
column
is the current note. "S" stands for Selected Entry. This is only
available on
MusicWriter Pro v2.0 and is used for cut/copy/paste. "Nt" stands for
note,
"Reg" for register, "Dur" for duration and "Tmp" for tempo. On
MusicWriter Pro
v2.0, if user flag 56 is set, there will be a "Frq" standing for
frequency
instead of "Nt" and "Reg" and if user flag 57 is set, there will be a
"Sec"
standing for seconds instead of "Dur" and "Tmp". If this is what you
have,
press the minus key for flag 56 and/or the plus key for flag 57 to clear
these
user flags until the top line displays "CS Nt Reg Dur
Tmp".
The last line is called the Message/Input Bar. Most of the time, this
line
will display the entry you are currently working on and the total number
of
entries. In MusicWriter Pro v2.0, an asterisk followed by a number
appears
when you select an entry for cut/copy/paste. This line also tells you
whether
the beep flat -56 is clear or not using a "S" annunciator. If you do not
see
the "S", clear system flag -56 by pressing the +/- key.
Everything in between the Field Bar and the Message/Input Bar is called
the
Note Display Area. Up to five notes can be displayed in this area - up
to two
before and/or after the current note. The current note (the one that can
be
immediately edited) is always in the middle with an arrow pointing at it.
Since we just started MusicWriter, there is only one note displayed (this
is
the default value - middle C for 1 beat at a tempo of 60). "CN" stands
for
C-natural, register 3 is the register containing middle C, 1 is the
duration
and 60 is the tempo (beats per minute). A "F" following the note name
would
make it a flat and a "S" following the note name would make it a sharp.
For
instance, "BF" would be a B-flat and "FS" would be a F-sharp. A "R"
stands for
a rest.

6.1.1.1. Help Screens
Note that help is almost always available; if you forget a keystroke, or
to
list all possible keystrokes on a certain screen, just press the HELP
menu key.
To exit the help screen, press any key.
6.1.1.2. Canceling an Editing Option
If you invoke an editing option by mistake, pressing CNCL will always
bring you
back to the Main Editing Screen (screen 1).
6.1.1.3. Editing Note Names
The very first note in the birthday song above is a G-natural. Change
the CN
to a GN by pressing NOTE (first menu key) and then G (fifth menu key). A
"natural" note can be obtained in this manner. If a piece that you are
working
on has notes that have flats or sharps, use left-shifted note names for
flats
and right-shifted note names for sharps.
6.1.1.4. Editing Register, Duration, Tempo, Frequency or Seconds
Pressing REG, DUR, TMP, FRQ (MWP20, flag 56 set) or SEC (MWP20, flag 57
set)
will invoke numeric editing. In this mode, you can use the numeric
keypad (0
through 9 and the decimal) to enter values. Use backspace to correct any
mistakes.
Change the duration of the first note by pressing DUR and entering .5
(press
ENTER after putting in the value). Next, change the tempo to 120 by
pressing
TMP and entering 120. Note that the register (3) is the same so it does
not
need editing.
6.1.1.5. The Up and Down Arrow Keys
The up arrow key moves the current entry pointer up one entry, the leftshifted
up arrow key moves the pointer up four entries, and the right-shifted up
arrow
key moves the pointer to the first entry. Similarly, the down arrow key
moves
the pointer down one entry, the left-shifted down arrow key moves the
pointer
down four entries, and the right-shifted down arrow key moves the pointer
to
the last entry. If the down arrow key is pressed when the pointer is on
the
last entry, the program adds another entry, copying the values from the
entry
the pointer was on. Pressing any of these keys or key combinations
"beeps" the
current entry before the pointer moves. To turn this sound off, press
the +/key to set flag -56.
Getting back to the birthday song, press the down arrow key to add an
entry.
Note that both the first and second entries are the same. Entry 2,
therefore,
does not require any editing. Press the down arrow key again.
Go ahead and change the note and the duration of entry 3.
6.1.1.6. The Left Arrow Key
The left arrow key "beeps" the current entry without moving the pointer.
Try
this on the A-natural that you just put in. This is a convenient way to
hear
what the note sounds like without having to move the pointer.
6.1.1.7. Insert and Delete Functions
Press the down arrow key. The pointer should be on entry 4. For the
sake of
this demonstration, put in the values for entry 5 instead (C-natural,
register
4). INS inserts an entry above the pointer, copying values from the
entry
above that. Press INS. The pointer should be pointing at the newly
inserted
entry. Change the AN to a GN. To get to entry 6, press the down arrow
twice.
The backspace key deletes the current entry.
to
get rid of entry 6.
Try it now; press backspace
6.1.1.8. Rests
Press the down arrow and put in the values for entry 6 (B-natural can be
found
on the second page of the note edit menu). Press the down arrow key.
Entry 7
is a rest. Entering rests are as easy as entering a note. Press NOTE,
NXT and
then R.
6.1.1.9. Turning the Calculator Off
The calculator can be turned off in the middle of the program. From the
Main
Editing Screen, press right-shift OFF. You can resume writing music when
you
turn the calculator back on.
If you are using MW50, try to finish the rest of the birthday song by
yourself.
After you finish entry 27, do not press the down arrow key. Skip to
section
6.1.3. If you are using MWP20, continue with the next section. The
following
sections deal with advanced features available only on MusicWriter Pro.
6.1.2. Additional Features: MWP20
In addition to the editing features described in section 6.1.1, MWP20
provides
cut/copy/paste, frequency and seconds editing and Current Entry View
editing.
6.1.2.1. Playback
MusicWriter Pro allows you to hear all or parts of the piece being worked
on.
Let us hear what the birthday example sounds like up to this point. Go
to the
first entry by pressing the right-shifted up arrow key. Press the right
arrow
to mark this entry. Note that an asterisk appears in front of the entry
and
the marked entry number appears right above the menu labels. Pressing
the
right arrow key will make the marked entry the current entry. Go to the
last
entry by pressing the right-shifted down arrow key. Make sure the "S"
annunciator is on (pressing +/- toggles it on and off) and press BEEP.
Everything that is "selected" (all entries between the marked entry and
the
current entry, inclusive) is played.
6.1.2.2. Cut/Copy/Paste
Note that the next four entries (entries 8 through 11) are exactly the
same as
entries 1 through 4. Press the right-shifted up arrow key followed by
the
right arrow key. Move down to entry 4 using the down arrow key. At this
point, there are three cut/copy/paste options. CUT cuts out the selected
entries for pasting. DEL deletes the selected entries (caution: no
undo!).
What we want to use is the remaining option: COPY. Press COPY. The
selected
entries are copied on to an imaginary "clipboard" and is now ready for
pasting.
The PASTE option inserts the entries from the "clipboard" to above the
current
entry. However, we want the four entries to appear after the last entry
so
press LAST. Move the pointer to the last entry by pressing the rightshifted
down arrow key.
6.1.2.3. Frequency and Seconds Editing
Pressing the minus key sets user flag 56 for frequency editing. Press
the
minus key. Note that notes and registers are replaced by frequencies.
This
allows the user to edit frequency values. This is useful when trying to
obtain
notes that cannot be labeled by a note name (a note between G and Gsharp, for
example). Press the minus key again to return to normal format.
Pressing the plus key sets user flag 57 for seconds editing. Press the
plus
key. Duration and tempi are replaced by seconds. This allows the user
to
enter lengths of notes in seconds.
normal format.
Press the plus key again to return to
6.1.2.4. Current Entry View
The Current Entry Viewer (invoked by pressing ENTER) may come in handy
for
viewing (and editing) detailed information about the current entry.
Press
ENTER. The top line displays the current entry number and the total
number of
entries as well as the status of the sound flag (-56). In the center,
complete
information about the current entry is given. Press ENTER to return to
the
Main Editing Screen.
Try to finish the rest of the birthday song by yourself.
finish
entry 27, do not press the down arrow key.
After you
6.1.3. Exiting MusicWriter and Storing the List
If you pressed the down arrow key by mistake after entry 27, press the
backspace key to "drop" entry 28. Otherwise, the last note will be
played
twice. To exit MusicWriter, press STO. The birthday song is translated
into a
list of complex numbers and is left on level 1 of the stack.
Store this list in a variable called 'BIRTHDAY'. Keep in mind that the
STO
function in MusicWriter is just for exiting the program; the program does
not
store the list for you.
If you would like to hear this example, see section 6.2.
6.1.4. Another Example Using MWP20
The following example deals with MusicWriter Pro.
you
may want to skip this section.
If you are using MW50,
Start MusicWriter Pro (MWP20, NEW) and enter the following data exactly
as
shown:

120
After you finish, press STO and store the list as 'SHAVE'. Recall the
list to
the stack and execute MPLAY. It should sound familiar, but there is
something
wrong with it; there should be another GN between entries 2 and 3!
6.1.4.1. Editing Lists
To make the correction, once again recall SHAVE to the stack and execute
MWP20.
Select EDIT. Note that despite the bar at the top reads "CS Nt Reg Dur
Tmp",
only frequencies and seconds are shown. When the EDIT option is
selected, this
always happens.
261.4 hertz is the frequency value for middle-C. The missing G-natural
belongs
in between the second and third entries. Move to the third entry and
press
INS. Note that the values from the previous entry, entry 2, are copied
into
the new entry. Press STO. Resave the list in 'SHAVE'. Recall the list
and
execute MPLAY. It should sound correct now.
6.2. GC and MPLAY
The program MPLAY plays music. It requires in stack level 1 a list
containing
complex numbers in the form (f,d) where f is the frequency and d is the
number
of seconds. A frequency of 0 would result in a silence or a rest. The
complex
numbers must be in reverse order to be played. The beep flag -56 must be
clear.
A "garbage collection" may occur between notes being played, resulting in
an
abrupt gap. The program GC forces garbage collection. Use this program
right
before executing MPLAY. Gaps may occur inevitably if your memory is
limited.
To play the birthday example, recall BIRTHDAY to the stack, execute GC,
then
MPLAY.
6.3. MADJ
MADJ is a music adjustment program. It requires a list usable by MPLAY
in
stack level 2 and a real number in level 1. A non-negative number will
adjust
the duration; a negative number will adjust the frequency. A positive or
negative 1 will not affect the list. A zero will change the duration of
every
note to a zero, but this list will not work with MPLAY. A positive
number
greater than 1 will make the notes longer; a positive number less than 1
will
make the notes shorter. A negative number less than -1 will make the
notes
higher; a negative number greater than -1 will make the notes lower.
Recall the birthday example to the stack, enter .5 and execute MADJ.
Execute
GC followed by MPLAY. Note that the piece is twice as fast as the
original.
Once again recall the birthday example to the stack. Enter -2 and run
MADJ.
Execute GC followed by MPLAY. The same piece is played an octave higher.
6.4. MC and Other Compression Options
MC is a music compressor/decompressor. If you write a lot of music, you
will
notice that memory is an important matter. MC compresses music lists
into
strings and vice versa. The strings created by MC cannot be used by
MPLAY.
Another option to consider is Lutz Vieweg's Redundance Fighter (RF)
programs.
The RF programs can compress music lists like nothing else. In terms of
both
time and memory, RF is a better choice over MC. The following is a list
of
pros and cons of each program.

notice.
MWPV displays the MusicWriter logo. Press any key to return to the

These two programs do not affect PICT or PPAR.
7. MusicWriter Sample Directories
There are seven different directories, each containing six samples. Each
directory comes in three formats: original, MC compressed and RF
compressed.
Samples compressed with MC and RF must be decompressed with MC or RFU
before
playing.

8. Questions and Answers
Q: When I try to start MusicWriter, an "Undefined Local Name" error
occurs.
What am I doing wrong?
A: The Last Stack is disabled. Enable Last Stack and restart the
program.
Q: In the previous versions of MusicWriter and MusicWriter Pro, editing
the
register when the note was a rest caused the program to error. Has
this
bug been fixed?
A: Yes. In both MW50 and MWP20, if REG is pressed when the note is a
rest,
the program ignores it.
Q: I accidentally deleted selected entries in MWP20. Is there any way I
can
recover what I deleted?
A: No. The "undo" feature is not available on any MusicWriter program.
Take
extra caution when using features such as CUT and DEL.
Q: The ATTN key no longer aborts the program. Why?
A: Out of panic, perhaps, some users tend to press the ATTN key when
they want
out of something that they got into by mistake. Except that they not
always want to leave the program. In MW50 and MWP20, the ATTN key is
ignored to prevent aborting the program by accident. If you want out
of
the program, just press STO and DROP the list.
Q:
A:
in
Why is STO the exit key rather than ENTER?
Because ENTER is used to input numeric values (as well as change view
MWP20), it is very possible the user might press ENTER when he or she
does
not want to exit.
Because of this, the STO key is a better choice.
Q: Why does MWP20 use user flags 56 and 57 for frequency and seconds
edit?
A: It is easier to remember because of the logic: system flags -56 and 57
deal with sound.
Q:
Where did the library ROM ID numbers 1136 and 1151 come from?
A: 1136 is the sum of the HP-48 character codes for each of the
characters in
the string "MUSICWRITER PRO" plus one (since this is the second
library
version) and 1151 is the sum of the character codes for each of the
characters in the string "MusicWriter" plus one.
Q:
A:
The MPLAY program is not working. What am I doing wrong?
The beep flag (-56) is probably set. Clear the flag and then run the
program.
Q:
A:
Why are there "gaps" when the calculator is playing?
The calculator is doing a "garbage collection." To prevent this from
happening during play, run GC right before playing music. Depending
on the
amount of memory you have available and the size of the list, a
"garbage
collection" may inevitably occur during play.
Q: MPLAY was previously known as PLAY. Why did you decide to abolish
this
tradition?
A: The variable PLAY is used so often for games, that a name conflict is
possible (since this is a library).
Q:
Is it possible to compress a list with MC first and then compress the
resulting string with RF?
A: Yes it is, but it isn't worth it. First, it takes too much time to
compress and decompress. Second, RF by itself can achieve close
results in
a fraction of the time.
